Mountain Home Idaho
The presence of lava rock will sometimes dictate the shape of your ground loop pit or trench. It certainly is not a show stopper though. We simply trucked in some clean top soil to bed our loop pipe. Once the slinky loops are covered, you can then backfill with the native soil / rock and be confident that your pipe is safe. This loop is serving a 5 Ton WaterFurnace Envision and a 3,800 sqft new home.
